Embodiment Construction

[0091] A rapid assessment method for earthquake landslide disasters, described in conjunction with the "4.20" Lushan earthquake in 2013, is characterized in that it includes the following steps:

[0092] 1) Within 2 hours after the earthquake, implement the first quick assessment—rough assessment;

[0093] 1.1) Within 5 minutes after the earthquake, according to the "China Seismic Station Rapid Report", basic information was obtained: earthquake time: 2013-04-2008:02:46.0, latitude: 30.3, longitude: 103.0, focal depth: 12.3km, magnitude : Ms7.0; epicenter location: Lushan County, Ya'an City, Sichuan Province (see figure 2 , image 3 ). in image 3 is the location of the earthquake in the 10°×10° area.

[0094] 1.2) Obtain key information such as terrain, landform, geological environment, and basic geographic data (1:4 million) in the earthquake-affected area based on Google Earth, Baidu Maps, and other information sources (see Figure 4 , 5 , 6, 7), implement the firs...

Abstract

The invention discloses a rapid assessment method for earthquake landslide disasters, which is characterized in that it comprises the following steps: within 2 hours after the earthquake, implement the first rapid assessment, that is, a rough assessment; within 3 to 6 hours after the earthquake, implement the second quick assessment The second rapid assessment is the preliminary assessment; within 8 to 12 hours after the earthquake, the third rapid assessment is based on the implementation of the key assessment; within 24 hours after the earthquake, the fourth rapid assessment is the fine assessment; Within 48 hours, implement the fifth rapid assessment, namely the revised assessment; within 72 hours after the earthquake, complete the sixth rapid assessment, namely the quantitative assessment. The present invention aims at the problems of time-consuming, low precision and large errors in rapid assessment of earthquake-induced landslide disasters. The assessment process fully considers the completeness of information, from rough assessment in the case of incomplete information to quantitative assessment in the case of relatively complete information. All disaster assessment work was completed within the "golden 72 hours" after the disaster.

Description

technical field [0001] The invention relates to the research field of geological disaster disaster prevention and mitigation and emergency management, in particular to a method for rapidly evaluating earthquake landslide disaster situation by applying multi-source information acquisition and comprehensive integration technology. Background technique [0002] Earthquake-induced landslides refer to the phenomenon that earthquake-induced slope rock (soil) slides downward for a certain distance along a gently inclined surface. Earthquakes are one of the main factors that trigger landslide disasters, and landslide disasters will be triggered when the magnitude of the earthquake is greater than 4.0. [0003] During strong earthquakes, landslides and secondary geological disasters induced by earthquakes, especially in mountain towns, often cause greater loss of life and property than those directly caused by earthquakes. [0004] Earthquakes occur frequently in my country, and mou...
